One of the requirements imposed on the realistic quantum computers is to provide computation results which can be repeated and reproduced. In the situation when one needs to repeat the quantum computation procedure several times, it is crucial that the copies of the quantum devices are similar in the sense of the produced results. In this work, we describe a simple procedure for based on variational quantum eigensolver which can be utilized to compare quantum devices. The procedure is developed by combining Choi-Jamio{\l}kowski isomorphism with the variational hybrid quantum-classical procedure for matrix diagonalization. We compare the introduced procedure with the scheme based on the standard bounds for the similarity between quantum operations by analysing its operation on random quantum operations.

量子器件的变体认证

对现实量子计算机的要求之一是提供可重复和再现的计算结果。在需要多次重复量子计算过程的情况下，至关重要的是，量子设备的副本在产生的结果意义上是相似的。在这项工作中，我们描述了一个基于变分量子特征求解器的简单程序，可用于比较量子设备。该过程是通过将 Choi-Jamio{\l}kowski 同构与矩阵对角化的变分混合量子经典过程相结合而开发的。我们通过分析其对随机量子操作的操作，将引入的过程与基于量子操作之间相似性标准界限的方案进行比较。
